Depth—mean-flow equations have been derived.through 2-D mean simplification of integration for 3·D folw equations along depth,for super—critical flow in divergent chute with curved bed,in which the influenceof curvature,bed slope and bottom friction on flow are considered.Based on depth—mean—flow equations,characteristic equation system are presented.Numerical characteristic FDM solution has been given for a diver—gent chute with parabolic prismatic bed surface in engineering.Problems for irregular distribution of characteristic mesh points have been solved by interpolating adjustment of computation points for every time step,SO thatthe results can be used conveniently in practical application.
